KAJIAN EVALUASI LAHAN HUTAN JATI SISTEM BONITA DI KESATUAN PEMANGKUAN HUTAN (KPH) CEPU

Abstract

Keywords: Land evaluation method using forest inventory was conducted to study the characteristics of teak forest land in relation to teak productivity and degradation of teak forest land This research was aimed at determining the dynamics of the changes of site quality (bonita) in the teak forest in Pasarsore and Cabak Sub Forest Management Units (BKPH), Cepu Forest Management Unit (KPH). The methode used is the site index system approach in which is the tree height and age plant as variable. The Forest inventory data will be tested to find out the relationship between the influence factors of the teak forest land and the stand potential. Site selection studies was considered at an catchment area of Sub Unit Watershed Management (DAS) level while the observation point was determined based on the age stand class (KU) and the site system of teak forests Secondary data to determine the location were obtained from part of the forest management unit (RPKH), KPH Perum Perhutani. The results showed that the sites that have an increase in quality are 12.5%, a decrease are 42.5% and 45% are still stable condition .
